Gold Coast barista and aspiring model Josephine Georgiou, 17, has defended Madonna for exposing her breast when she was invited on to the stage during Thursday night’s concert at the Brisbane Entertainment Centre.

She mocked suggestions that she may sue the singer.

“Seriously, why would I sue Madonna for the best moment of my life?,” she told The Courier Mail.

“It was the best night.

“She was calling me a Victoria’s Secret model the whole time I was on stage, which is so flattering.”

A video of Madonna yanking at the teenager’s top to expose her breast has gone viral and made news around the globe.

Georgiou said she was wearing her mother’s corset and it was too big, which meant she was adjusting it on stage while Madonna was talking to the crowd.

She added she was not offended by the incident.

“Only I get to decide if I’m humiliated or not, why would people assume I am humiliated by my own breast, nipple or body?,” Georgiou said.

“It’s hilarious to me how much of a big deal it is to everyone, people just need to understand I was on stage in front of Madonna, I was looking her in the eyes and most people would just melt into a pool on stage, so it was only because I was standing in front of her that I looked so surprised.”

She also denied claims the incident was staged and insisted she was randomly plucked from the crowd.

The latest stunt by Madonna has not gone down well.

UK commentator Piers Morgan has called on the veteran pop star to cancel her Rebel Heart tour because she’s having a “meltdown”. “Madonna is in total meltdown. She needs to cancel this tour asap,” he tweeted on Friday.

Madonna was two-and-a-half hours late on stage on Wednesday for her first Brisbane concert, and four hours late on stage for a Melbourne show last week.

The tour ends on Sunday at Sydney’s Allphones Arena.
